In changing the mounting tabs inside the cowling of my DHC-2 Beaver from a screw mounting system to magnet mounts, I had to debond three of the four new mounting tabs and will be re-installing them. The debonder did its job effectively but I am left with a mess of sticky, gooey residue. After trying more debonder, then alcohol, neither of which has been effective, it occurs to me that somebody more experienced than I probably has the answer to this cleanup challenge. Thanks in advance for your help. Ron
